Hello everyone, today I reconsidered the internal representation of the feed / entries. I had a closer look at the Google Data Client Api which is supposed to be the other end to the server. This API is dist. under the Apache Licence e.g. open source. It already provides the Object representation of feeds and entries. The API provides very handy interfaces to extend the protocol and the project could benefit from new versions. I would rather go for using the api to work with feeds and entries inside the server than implement the whole api again.
